Why You’ll Love This Peanut Butter Banana Muffins
- The aroma alone is worth the effort. The moment those bananas hit the warm oven, your home fills with a deep, sweet fragrance that feels like a hug. It’s the sort of scent that makes everyone wander into the kitchen, asking, “What’s baking?”
- They are deeply, wonderfully moist. Overripe bananas and a generous dollop of peanut butter work together to create a crumb that is tender and almost pudding-like, without being heavy. I’ve been making this for over 3 years, and it never disappoints on texture.
- Perfectly balanced flavour. The natural sugar from the bananas meets the salty, savoury edge of the peanut butter. There is no cloying sweetness here, just a satisfying, grown-up harmony that makes you reach for a second one.
- A forgiving and adaptable dough. This batter is wonderfully robust. You can fold in chocolate chips, a handful of oats, or even some chopped dates, and it will still bake up beautifully. It’s a brilliant base for your own weekend experiments.
- They keep exceptionally well. Stored in an airtight tin, these muffins actually improve after a day. The flavours meld together, and the crumb becomes even more luscious. Perfect for making ahead for a week of leisurely breakfasts.
Ingredients You’ll Need
- 3 large, very ripe bananas (the spotty ones are best – about 350g peeled weight)
- 100g smooth peanut butter (unsweetened, no added sugar)
- 75ml sunflower or vegetable oil
- 100g light brown sugar
- 2 large eggs, at room temperature
- 1 teaspoon vanilla extract
- 200g plain flour
- 1 teaspoon bicarbonate of soda
- ½ teaspoon baking powder
- ½ teaspoon fine sea salt
- Optional: 100g dark chocolate chips or chopped roasted peanuts for the top
Tip: The ripeness of your bananas is the most important variable here. They should be soft to the touch and heavily speckled with brown – this ensures maximum natural sweetness and moisture. If your bananas are only yellow, the muffins will be less sweet and noticeably denser.
How to Make Peanut Butter Banana Muffins
- Preheat and prepare. Set your oven to 190°C (170°C fan). Line a 12-hole muffin tin with paper cases. The anticipation begins now, as the oven warms and you gather your tools.
- Mash the bananas. In a large bowl, peel and add the bananas. Use a fork to mash them until they are a chunky, lumpy purée. You want some texture remaining – a few pea-sized pieces are perfect. You should hear the soft squelch of them breaking down. Aim for a consistency that looks like a thick, sludgy porridge.
- Mix the wet ingredients. To the mashed banana, add the peanut butter, oil, brown sugar, eggs, and vanilla extract. Stir with a wooden spoon or spatula until everything is combined. The mixture will look a little speckled and glossy. It should smell intensely of peanut butter and sweet banana.
- Combine the dry ingredients. In a separate, smaller bowl, whisk together the flour, bicarbonate of soda, baking powder, and salt. This ensures the raising agents are evenly distributed, so you don’t get one lopsided muffin that rises while its neighbour stays flat. The flour should look light and aerated.
- Fold the batter together. Tip the dry ingredients into the wet mixture. Using a gentle hand, fold everything together with a spatula. Stop as soon as no streaks of flour remain. The batter will be thick, shaggy, and quite stiff – do not overmix, or the muffins will be tough. If you are adding chocolate chips, fold them in now.
- Fill the cases. Divide the batter evenly among the 12 paper cases. They should be almost full – about three-quarters full to the top. For a bakery-style dome, use a small ice cream scoop or two spoons to mound the batter slightly higher in the centre. If using, scatter a few chopped peanuts on top of each muffin.
- Bake until golden and fragrant. Place the tin in the centre of the oven and bake for 18–22 minutes. The muffins are ready when they are domed, a deep golden brown, and a skewer inserted into the centre of one comes out clean or with a few moist crumbs. Your kitchen will be thick with the scent of toasted peanuts and caramelised banana. The tops should spring back when lightly pressed.
- Cool completely. Let the muffins rest in the tin for 5 minutes – this allows them to set and makes them easier to handle. Then, transfer them to a wire cooling rack. The sound of them gently releasing from the paper is a small satisfaction. Let them cool completely before storing, as the steam can make the tops soggy if they are sealed too early.
Tips From My Kitchen
- Use room-temperature eggs. Cold eggs can cause the softened butter or oil to seize up slightly, making the batter curdled-looking and dense. Let your eggs sit on the counter for 30 minutes before you begin. If you forget, place them in a bowl of lukewarm water for 5 minutes – this brings them up to temperature gently and ensures a smooth, emulsified batter.
- Don’t overmix the batter. This is the cardinal rule of muffin-making. Once the flour hits the wet ingredients, gluten begins to form. Overworking the batter develops too much gluten, resulting in a tough, rubbery muffin rather than a tender, soft one. Stir only until you can no longer see dry flour – a few lumps are absolutely fine.
- Measure your peanut butter correctly. Peanut butter is sticky and easy to over-measure. For accuracy, lightly grease your measuring spoon with a tiny drop of oil first, or use the water displacement method: fill a measuring jug with 100ml of water, then add peanut butter until the water level reaches 200ml. This gives you exactly 100g without the mess.
- Check your oven’s temperature. Ovens can be notoriously inaccurate. An oven that runs too hot will give you burnt edges and a raw centre; too cool, and the muffins will be pale and flat. Invest in a simple oven thermometer – it costs very little and will transform your baking. If you see the muffins browning too quickly after 10 minutes, tent them loosely with foil.
- Let the flavours mature. Like many baked goods, these muffins taste even better the next day. The moisture from the bananas continues to distribute through the crumb, and the peanut butter flavour deepens. If you can resist, wrap them tightly and leave them overnight. Friends always ask me for this recipe after trying it at dinner parties, and I always tell them the secret is patience.
Equipment You’ll Need
- Stand mixer or hand mixer (though a wooden spoon works perfectly well, a mixer makes the job a little faster)
- 12-hole muffin tin
- Paper muffin cases
- Large mixing bowl and a smaller bowl for dry ingredients

What to Serve With Peanut Butter Banana Muffins
- A generous smear of extra peanut butter and a drizzle of honey for a truly indulgent breakfast.
- A steaming mug of milky coffee or a pot of strong English breakfast tea – the bitterness cuts beautifully through the sweetness.
- For a moreish afternoon treat, serve them alongside a bowl of thick Greek yoghurt and a handful of fresh berries.
- If you are in the mood for a proper dessert, warm one slightly and serve it with a scoop of vanilla ice cream. It is a simple, stunning end to a weekend meal.
- They also make a lovely, sturdy companion to a Nutritious Pumpkin Pie Smoothie Bowl Recipe for a very satisfying brunch spread.

Frequently Asked Questions
Can I use crunchy peanut butter instead of smooth?
Absolutely. Crunchy peanut butter will add lovely little pockets of texture and a more pronounced nutty flavour throughout the muffin. Just be aware that the pieces can sometimes sink to the bottom of the batter, so give the mixture a very gentle final stir just before spooning it into the cases to redistribute them.
My bananas aren’t ripe enough. Can I still make these?
Yes, you can speed up the ripening process. Place the unpeeled bananas on a baking tray in a 150°C oven for 15–20 minutes, until the skins turn completely black and the fruit feels very soft. Let them cool completely before using. This method caramelises the sugars, mimicking the sweetness of a naturally ripe banana.
Can I make these muffins gluten-free or vegan?
For a gluten-free version, swap the plain flour for a good-quality 1:1 gluten-free baking blend that contains xanthan gum. For a vegan adaptation, use two flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water, left to thicken for 10 minutes) and ensure your peanut butter and sugar are vegan-friendly. The texture will be slightly denser but still delicious.
How should I store these muffins, and how long will they keep?
Store them in an airtight container at room temperature for up to 4 days. To keep them extra moist, place a piece of kitchen paper inside the container to absorb excess moisture, but change it daily. They can also be frozen for up to 3 months – wrap each muffin individually in cling film, then place them in a freezer bag. Thaw at room temperature for an hour or warm gently in the microwave for 20 seconds.
Why did my muffins stick to the paper cases?
This usually happens if the muffins are not fully cooled before storing, or if you used a lower-quality paper case. The steam trapped inside softens the paper and makes it stick. Always cool the muffins completely on a wire rack before wrapping them. You can also try using foil cases or lightly greasing the paper cases with a little spray oil before filling them.
